The Materials Map is an open tool for improving networking and interdisciplinary exchange within materials research. It enables cross-database search for cooperation and network partners and discovering of the research landscape.

The dashboard provides detailed information about the selected scientist, e.g. publications. The dashboard can be filtered and shows the relationship to co-authors in different diagrams. In addition, a link is provided to find contact information.

Materials Map under construction

The Materials Map is still under development. In its current state, it is only based on one single data source and, thus, incomplete and contains duplicates. We are working on incorporating new open data sources like ORCID to improve the quality and the timeliness of our data. We will update Materials Map as soon as possible and kindly ask for your patience.

Abstract

<jats:title>Abstract</jats:title><jats:p>Ultra-low resistance joints are a key technology enabling superconducting magnets to operate in persistent mode and to achieve the temporal stability required for nuclear magnetic resonance (NMR) and magnetic resonance imaging (MRI) applications.High performance superconducting joints are manufactured routinely for Nb-Ti and Nb3Sn magnets, but technologies for joining other technological superconductors are still in the early stages of development.Here we report the use of a simple cold pressing and heat treatment procedure to fabricate persistent MgB2 joints with resistance values &lt;10-12 Ω between MgB2 wires that have already undergone the full wire reaction process. Trapped persistent currents of 172 A and 160 A were respectively achieved under self-field and 1 T background field conditions at a temperature of 20 K. This corresponds to a critical current ratio of 78% under these conditions, outperforming previously reported joints using fully reacted MgB2 wire. These findings are relevant for the development of commercial magnetic resonance imaging (MRI) magnets with MgB2 wires utilizing react and wind methods.</jats:p>
